In some cases, we have to convert the String variable into a Byte array format, for example, JCE encryption. However, how do we convert a Byte[] array to a String afterward?
Simple toString() function like the following code is not a working property. It will not display the original text but the byte value.
String s = bytes.toString();
In order to convert the Byte array into String format correctly, we have to explicitly create a String object and assign the Byte array to it.
String s = new String(bytes);
And here’s a sample code:
public class TestByte {
public static void main(String[] argv) {
String example = "This is an example";
byte[] bytes = example.getBytes();
System.out.println("Text : " + example);
System.out.println("Text [Byte Format] : " + bytes);
System.out.println("Text [Byte Format] : " + bytes.toString());
String s = new String(bytes);
System.out.println("Text Decryted : " + s);
}
}
Output
Text : This is an example
Text [Byte Format] : [B@70fccc53
Text [Byte Format] : [B@70fccc53
Text Decryted : This is an example
